Battery
A built-in lithium battery buffers the data in the RAM memory and also supplies the
real-time clock with power. The discharge degree of the battery is monitored con-
stantly to prevent any loss of data.
The battery provides a minimum life of 5 years, even under unfavourable operating
conditions.
If the battery is drained the system message ‘change battery’ is generated.
A new battery is supported by OMRON EUROPE.
Replacing the battery:
The battery can be replaced while the operating voltage is connected to ensure that
the message data and time setting are not lost. Mind the safety instructions!

Remove the mounting bolts of the 25-pin interface connector
-
Remove the fastening screws of the enclosure and remove the enclosure
-
Replace the cable fastener, which is used to fasten the battery
